("" \ ( * ,,,, * ) / "") - Hi! Sorry for my hard in english.--------------------------------------------------------------I have a problem with multi-channel playback.Sound heard only of four speakers (FL, FR, RL, RR). Central channel (Subwoofer+FC) does not work, but if the jack is inserted at the half,then heard a sound from the subwoofer. Once I had a similar problem on Win XP - then helped the option "bass redirection" in sound card driver.The audio card is: Sound blaster Audigy 4 Model SB0610.The speaker system: Microlab A-H500D.--------------------------------------------------------------uname -a:

Try multichannel output is /dev/oss/oss_sblive0/pcm5 , but I see you tried to symlink pcm0. Maybe you tested the wrong output? Test for pcm5. Second, try changing SPKMODE in the mixer controls. Third, if you change oss_sblive.conf, note that OSS restart (soundoff && soundon) is needed to get the settings.

Thank U for a quick reply!)If I try to test multichannel output /dev/oss/oss_sblive0/pcm5 (for example:"cat /dev/random > /dev/oss/oss_sblive0/pcm5" or when I choose this device as an output in VLC ) it is appeared an error in terminal "panic double fault" and the computer begins to reboot after 15 sec. I tested it also with another computer (FreeBSD 8.1/OSS 4.2), by moving this sound card, but it was the same error and computer restarting, so no result! And what about the second and the third points - I've also tried & it was no result!!!P.S. I suppose that if the jack is inserted at the half and it is heard the sound from the subwoofer, the problem may be in redirection or remapping of output signals....

Well, it's not the same issue.. It's the oss_sblive driver not playing well with the audigy's spdif output. I recall someone on Linux having the same issue, so it is not FreeBSD specific. Alas, I don't know enough to help you here. It may be a much earlier version of OSS didn't have this problem (or maybe not).

Oh, yes, that's my mistake, sorry. I'm not using SPDIF. So, i shouldn't use /dev/oss/oss_sblive0/pcm5. Thank you for showing the right way! I will continue to looking for the reason of missing center/sub.

Sorry, I've been very busy... I'm not entirely sure what you mean by 'no sound with other players'. osstest probably plays via the center because it (eventually) reaches the right dsp node. I think other players should be able to play if they are pointed to it... Can you check what that node's name is?

As for getting it to work combined with the other outputs, well, I found out the muxing for the 5.1 output is done by the remux function (see kernel/.../remux/ subdir in the source). If we can find out why it crashes, we should be able to get it to work combined.

Oh, i'm very very sorry, there is a mistake because of my inattention. Osstest starts to play center out after I've set SPKMODE to DISCRETE. I checked it again and if sblive_devices is default (with SPKMODE DISCRETE), osstest still play center out. But it is playing just when it test center/lfe channel. When "SB Audigy4 main" is testing, there is a sound just from FRONT. The same is when i try to listen audio in players (audacious, vlc), that use /dev/dsp for output. If i select any other item of the SPKMODE (FRONT, SURR, FRONT+SURR), osstest and players output the sound through selected channels (just front, just rear, front and rear together), nevertheless what channel is testing.My current settings:ossmix -a
